New Evidence Confirms What Gun Rights Advocates Say About Crime

In the study, led by epidemiologist Anthony Fabio of Pittsburgh's Graduate School of Public Health, researchers partnered with the Pittsburgh Bureau of Police to trace the origins of all 893 firearms that police recovered from crime scenes in the year 2008.

They found that in approximately 8 out of 10 cases, the perpetrator was not a lawful gun owner but rather in illegal possession of a weapon that belonged to someone else. The researchers were primarily interested in how these guns made their way from a legal purchase — at a firearm dealer or via a private sale — to the scene of the crime.

"All guns start out as legal guns," Fabio said in an interview. But a "huge number of them" move into illegal hands. "As a public-health person, I'd like to be able to figure out that path," he added.

More than 30 percent of the guns that ended up at crime scenes had been stolen, according to Fabio's research. But more than 40 percent of those stolen guns weren't reported by the owners as stolen until after police contacted them when the gun was used in a crime.
